FAQs

Q: Does this unit operate standalone?
A: No. As a fabric extender, it requires a compatible parent switch for control and forwarding.

Q: Are any SFP or SFP+ transceivers included?
A: Transceivers are not guaranteed and may be bundle-dependent. Verify contents before purchase.

Q: Can I choose airflow direction?
A: Yes. Matching fan and power module options provide either port-side intake or port-side exhaust.

Q: Is PoE supported on the host ports?
A: No. Host ports are data-only SFP interfaces (100/1000).
